uAvionix has announced U.S. Federal Aviation Administration (FAA) approval of the Vehicle Tracking Unit (VTU-20) Automatic Dependent Surveillance – Broadcast (ADS-B) transmitter for airport surface management.

uAvionix is a designer and manufacturer of communications, navigation and surveillance (CNS) equipment for unmanned and manned aircraft.

Adhering to the performance and design assurance specifications of FAA-E-3032, the externally mounted VTU-20 ensures integration and interoperability with Airport Surface Detection Equipment, Model X (ASDE-X), Airport Surface Surveillance Capability (ASSC) and ADS-B receiver surveillance solutions for airport
surface control and situational awareness.

The VTU-20 can be permanently or magnetically mounted to all airside vehicles, including utility, emergency, snow-removal and maintenance equipment. Each vehicle is clearly and uniquely identified, providing an essential addition to any surface movement guidance and control system.

The VTU-20 implements FAA-approved Squitter Transmission Maps to automatically enable transmission on airport movement areas and disable transmission in low-risk areas or outside airport airside operations.

“Ground vehicle incursions into critical safety and movement areas is on the rise. With this achievement, uAvionix continues to promote safety and common situational awareness not only in the airspace but also on the airport surface,” states Christian Ramsey, uAvionix president.

This recent uAvionix achievement will be made available through an exclusive relationship with L3Harris Technologies, Inc., a leader in surveillance and air traffic management known for the Symphony product line of airport operations and environmental compliance solutions — to promote and sell the VTU-20 in the United States.
